Title: Culturing epithelial cells in a medium containing a barbituric acid derivative
Inventor: SATO JIRO
IPC: C12N1/38
Filed: 1985-05-11
Abstract: Addition of a barbituric acid derivative enables normal epithelial cells, which might survive for only one week at the best in the absence of a barbituric acid derivative, to survive for as long as approximately one month, thus making prolonged culture possible. The method of the present invention contributes to effective studies on normal epithelial cells and efficient preparation of large amounts of various physiologically active substances produced by normal epithelial cells.

Title: Flashback arrestor
Inventor: BUTCHER EDWARD ALBERT ARTHUR
IPC: F23D14/82
Filed: 1985-09-10
Abstract: A flashback arrestor (1) for a gas torch comprises a body (2) accommodating a flashback arrestor element (5), the body being further provided with a spring loaded self sealing valve 6. The element is porous and of material of high thermal conductivity, and has a cylindrical or tubular wall and a closed end. A gas flow pocket or recess (19) is provided between the body and the flashback element and communicates with a space (14) in the body exteriorly of the wall of the element. A gas flow path extends through the valve, through the cylindrical or tubular wall of the element to the space (14) at the exterior thereof and through said at least one pocket or recess to a space (9) adjacent the closed end of the flashback arrestor element. When an appliance is attached to the arrestor by means of a nut (3), a valve element 7 of a further valve lifts an O-ring 24 from its seat to allow gas flow through the arrestor. <IMAGE>

Title: Segmented carbon-carbon exit cone assembly
Inventor: GIEDT DONALD C
IPC: F02K1/00
Filed: 1985-10-17
Abstract: An exit cone (10) for solid propellant rocket motors or liquid propellant rocket engines is fabriÂ­cated as discrete carbon-carbon segments (12) and subsequently assembled into a cone. Preferably, longitudinal and circumferential supporting stiffÂ­eners (32,34,44) are formed integrally therewith. This segmented construction means that if one part of the cone is flawed or damaged, it is necessary only to replace that part rather than the whole one.

Title: Detecting tampering with meters
Inventor: COHEN EMMANUEL
IPC: G01R21/08
Filed: 1985-11-23
Abstract: To detect tampering, an electricity meter (1) comprises a device (11,12) providing a first output representative of the current through the live conductors (6,8) and a device (26,28) providing a second output representative of the current through the neutral conductors (7,9). A third output is generated (29,30) representative of the difference between the currents in the live and neutral conductors. The second and third outputs are summed (34) to provide a fourth output, and the first and fourth outputs are compared (38). A tamper detection output is generated (39) when the difference between the first and fourth outputs exceeds a predetermined threshold. The third output, alone, may be used to supply an earth leakage detector circuit. <IMAGE>

Title: Utility meter
Inventor: SELPH MARVIN PATRICK
IPC: G01R21/08
Filed: 1986-04-16
Abstract: The utility meter (20) is a microprocessor-based circuit using Hall effect electric current sensors to measure power usage by residential and commercial customers. An analog signal from the Hall effect sensor is converted to a digital signal which is fed to the microprocessor for analysis and storage in random access memory. Using a real time clock, the microprocessor determines time of use information which is also stored in random access memory. The memory may be remotely interrogated via a telephone line (32) or serial communication link. If desired, the meter can receive utility usage inputs from other utility meters, such as water, (38) gas, (40) etc. <IMAGE>

Title: Automatic reversing tape recorder
Inventor: YOSHIMURA TOSHIO
IPC: G11B15/44
Filed: 1988-05-18
Abstract: On reversal a pinch roller changeover mechanism, coupled by arm 39 through resilient pins 61a, 61b, drives a slider 36 which through gears 33, 32, rotates the head 14 mounted in the cylindrical rotary member 15. The arm 39 overdrives to leave spring pressure to hold the head firmly in its limit positions. In place of flexible fingers 61a, 61b, spring pressure at the limit positions may come from an over-dead-centre spring (44) between the slider and the gear 33. Head rotation is limited by tab 16 engaging stops 26a, 26b , which are bifurcations at the ends of a wave-shaped spring plate 23, the adjacent limbs of the bifurcations being flexibly secured by adjusting screws. The head is rotated while still in contact with the tape. Changeover is governed by a trip gear (56) rotating in 180 degree steps. <IMAGE>

Title: Brake fluid pressure control apparatus for slip and traction control
Inventor: ARIKAWA TETSURO
IPC: B60T8/48
Filed: 1988-10-26
Abstract: Fluid pressure control valve devices 4a, 4b are arranged between a master cylinder 1 and wheel cylinders 7a, 7b of a vehicle, the fluid pressure control valve devices receiving control signals Sa, Sb from a control unit 31 measuring wheel skid condition to control the brake fluid pressure to the wheel cylinders. A hydraulic reservoir 25, when the brake fluid pressure to the wheel cylinder 7a is decreased according to control of the fluid pressure control valve devices, reserves the brake fluid discharged through the fluid pressure control valve devices from the wheel cylinders. Pressure fluid supply conduits 3, 16 connect the master cylinder 1 with the fluid pressure control valve devices and fluid pumps 20a, 20b return the brake fluid from the hydraulic reservoir 25 into the pressure fluid supply conduit 3, 16. A valve apparatus 8 is arranged in conduits 42a , 42b and has a balanced central piston and provides a diagonal brake split. During split  mu  slip control the valve apparatus allows the brake fluid pressure to cylinder 12a to be reduced in line with pressure to cylinder 7a whilst allowing pressure at cylinders 7b and 12b to remain unchanged. The timing of the pressure changes to cylinder 12a is related to the timing periods of pressure change to cylinder 7a.
